Course Description

This course is aimed at Systems Programmers, Programmers and DBA's who are moving from DB2 Version 8 to DB2 Version 11 and therefore need to understand the new features and facilities of DB2 Versions 9, 10 & 11. This lecture based three-day course covers all of the new features in detail.


Pre-requisites

A strong working knowledge of DB2 Version 8 is required to attend this course.


Objectives

The aim of this course is to provide the delegate, familiar with DB2 V8, with the necessary skills required to use the new Version 9, 10 & 11 features.


Environment

The lectures apply to DB2 running in a z/OS environment.


Customisation

For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.
